The Museum’s mission is to collect, preserve, document, exhibit, research, study and interpret objects relating to natural and cultural history, primarily of South Dakota and surrounding areas. To further our mission, the museum develops interpretive exhibitions, programming, contributions to publications, guided tours of the museum, relationships with researchers and more. To support the W. H. Over Museum & its mission, please feel free to donate in the PayPal link below.

As a means of supporting the museum, the Friends of the W. H. Over Museum was founded in 1967. In 1973, the management of the museum passed from USD to the South Dakota Cultural Preservation Department. Following the loss of State funding in 1996, the Friends of the W. H. Over Museum incorporated to run the museum with the help of few paid staff and dedicated volunteers. Support the museum and donate today!
